How it is worked out
100 × Opp PTS ÷ Opp POSS
Worked through
Seventy-eight points allowed in 72 possessions is 108.3. Subtract it from that game’s 113.9 offensive rating and the net is +5.6.
What it leaves out
An individual DRtg is an estimate apportioned out of team numbers, not points this person actually gave up. It flatters bigs and punishes guards, so player-to-player comparisons are unsafe.

One term down, the whole sheet to go
The numbers on a sheet lean on each other. How many free throws appear depends on the team foul count; how many rebounds exist depends on how both teams shot. Reading a whole game means reading them together.
